Membranes that treat the world’s toughest wastewater

The solution to your filtration needs

Our patented, zwitterionic membranes can handle unprecedented levels of oil and grease without irreversible fouling, recovering full performance.

Paving the way for affordable water reuse

Our membranes make it possible to treat historically unfilterable streams. We enable customers to manage and recover value from water, transforming waste from a cost to a benefit.



Implement high-quality treatment to stay below your organic discharge limits.

Water Reuse
Meet and exceed your sustainability goals with permeate that is easy to reuse.

Process Efficiency

Less time and chemicals are needed for cleaning, allowing more time to run your operations.

Product Recovery

Isolate valuable compounds using membranes with precise, size-based rejection.

Cutting-edge chemistry

Our zwitterionic materials produce hydrophilic (“water-loving”) polymeric membranes that are durable and resistant to fouling.

They clean easily and last longer than membranes made from traditional chemistries. We optimize water treatment and organic separations so you can reclaim the full value of your resources while reducing maintenance and overhead costs.
